Advantages of Pinch Valves
Pinch valves are simple in terms of their construction with very few parts and coupled with a full bore opening, making them ideal to handle fluids with high concentration of solids or abrasive products.
● Free passage
● Optimum tightness
● Low resistance
● No plugging
● Low air consumption
● No leakage – no bearings and seals
● Wear resistant sleeve
● Used for throttling applications
● Easy to control
● Few parts and inexpensive
Due to the pinch valve’s simplistic design, they only consist of the following components:
(A) Flanges / End Connections
(B) Body / Housing
(C) Sleeve
(D) Bolts & Nuts
